Patented Oct. 6, 1914.

Application filed December 29,1913. Serial No. 809,360.

To all whom it may concern:

Be it known that we, MICHAEL G. SWART- W001) and VERNON SwAnrwoon, citizensof the United States, residing at Manchester "and Clay Center, respectively, in the counties of Dickinson and Clay and State of Kansas, have lnvented certain new and usei ful Improvements in FilteringDevices, of

may flow at a moderate rate of speed to per- ,Init heavy substances or sediment to settle at the bottom of the filter, where it maybe readily drawn oil.

A further ob ect of the invention resides in providing a filter which is quickly and readily cleaned and one which maybe used to operate on asmall or largescale, such as domestic supplies and supplies for entire communities. I

Still another object of the invention resides in providing a device which is simple and durable in construction, inexpensive to manufacture and one which will be very efficient and useful inoperation.

With these and otherobjects in view, the invention consists in the novel features of construction, combination: and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specificationand claims. M

In the accompanying drawings forminga part of this application, Figure 1 is a vertical section through a device constructed in accordance with ourinvention. Flg. 21s a horizontal section as seen on line 2-2, of Fig. 1. Fig. 3 is a similar view as seen on line 33, Fig. 1. Idig. 14: is a plan View of the inner filtering casing-removed, Fig.5

Fig.7 is an enlarged detail section through the lower end of the filtering casing,,showing its supporting connection with a the supporting flange on the main casing. Fig. 8 1s a horizontal sectlon as seen onlme 8IS,,F1g. 1;

andIFig. 9 is a plan view of one of the bafiie plates used in connection withthe device.

In describing our invention, we shall refer to the drawings in which similar reference characters designate corresponding parts throughout the which- 1 indicates a main casing or housing,

which has the bottom 2 thereof inclined somewhat toward one side of the same. Leading to and communicating with theinterior of the casing or housing, at a point just above theuppermost point of the bottom, is an inlet pipe 3 which extends ivertiseveral views and, 1n

cally upward along one side of the casing to a point above the upper edge thereof. Leading to and communicating with thecasing or housing, immediately adjacentthe top thereof, and on the side opposite that to which the inlet pipe leads, is an outlet pipe at, which extends downwardly from the point of introduction into the housing and leads further to any desired point. f

Adapted to be mounted within thejcasing or housing 1, isa substantially cylindrical or other deslgned casing 5, the bottom 6 thereof being foraminous. This cylindrical casing is adapted to receive a filtering material 7, which material may be of the usual or any preferred character. Secured to the inner wall of the casing or housing land bent somewhat inwardly, is a supporting.

flange 8, w'hilethe lower edge of the casing 5 is provided with a downwardly and out wardly projecting flange 9 which is adapted to "be seated on the supporting flange 8 to support the casing 5 in the main casing or housing: 1. Arranged in the bottom ofthe supporting flange 8, is a packing 10 which makes a Water tight connection at such point and also affords a generally better construction than ordinarily.

A top 11 formed of foraminous material is provided for the cylindrical casing 5, said topbeing constructed as a perforated plate,

or screen, as desired and in order to secure said top 11 in place, locking lugs 12 are pro, 1

vided at the top of the casing 5, on the inner wall thereof. In order to permit the top 11 to be positioned, notcheslS are provided in the peripheral edge at diametrically opposite points thereon to permit said topto be disposed below said lugs and ontop of the filtering material 7. In placing the top in use, it is obvious that the notches 13 are po sitioned to register with the lugs 12 and said top is then given a partial rotation to dis pose the notches out of registration with the lugs. A locking strip 14- is provided for introduction at its ends under the lugs 12 to bind tightly against the foraminous top 11 and this strip forms a diametrical locking member to retain said top in place. This strip is off-set at its center, as shown at 15 to form a handle member or the like, whereby the casing 5 with its contents may be lifted, when desired.

In order to retain the casing 5 with the contents therein and top thereon in place in the main casing or housing 1, we provide the leaf springs 17. These leaf springs are secured at their upper ends tothe inner wall of thecasing or housing 1, adjacent its top and the same are bent outwardly toward the lower free ends thereof. These lower free ends are engaged with the top of the casing 5 and obviously lock the latter in position in the casing 1. In order to remove the casing 5 from the casing 1, said springs 17 must be first forced outwardly against the walls of the casing l, in order to release the engagement thereof with said member 5.

A plurality of perforated baffle plates 18 are provided adjacent the bottom of the main casing or housing 1, said plates being arranged in spaced relation and parallel to one another below the bottom of the casing 5 and suitably secured upon the horizontally disposed flange of an annular member 18 which is of angular cross sectional form and has its vertical flange fixed to the wall of the casing 1. Each of the plates 18 is provided-with a plurality of openings 18 arranged in staggered relation, the openings in one plate being disposed out of register ing relation with the openings in an adjacent plate. These plates are arranged in alinement with the inlet opening of the easing or housing 1 and are adapted to retard the current of the water entering said casing 1 from the inlet pipe. By retarding the current in this manner, the same is caused to flow evenlyupward through the filtering casing 5 and all extraneous matter and substances, to gether with the sediment will be deflected and caused to settle on the bottom 2 of the main casing or housing 1. A discharge fau- ,cet 19 is provided in the wall of the casing or housing 1, adjacent the lowermost portion of the bottom 2, to admit of the sediment being readily removed, when desired. to be observed that the plate nearest to the faucet 19 is spaced a considerable distance from the next plate 18, the remainder of said baffle plates being equally spaced apart as clearly shown in Fig. 3. By providing this wide open space above the inclined catch basin 2, it will be appreciated that the plates 18 offer no impediment to the collection of such as domestic use. twigs, branches, leaves and the like are the sediment in the lower end of the basin so that it may be readily withdrawn therefrom when the faucet is opened. I

This device is adapted for use in connection with large plants or on smaller scales, In either instance,

adapted to flow with the water toward the filter and we have also provided a means for removing such substances prior to the entrance of the water to the filter proper. To this end, a rectangularhousing 20 is provided, from the top and bottom of which project the tubular portions 21 and 22, respectively. The lower projecting tubular portion 22is adapted to be received in the upper end of the inlet pipe 3 and the opening between the housing20 and the lower tubular portion 22 is covered by a plurality of diagonally extending rods 23. This housing 20 is entirely closed, with the exception of the front wall thereof and a hinged door 24 is provided for the front wall which is formed of foraminous material, which is a perforated plate or screen, preferably the latter. Thus, as the water flows toward the inlet pipe 3, the twigs, leaves and the like will be received on the grading formed by the rods 23"and may be readily removed by the opening of the door 24.

We have provided a top for the entire device, indicated as 25. The same is provided, on its under face, adjacent its outer peripheral edge, with an angular and depending flange 26 and is designed to fit within the wall of the casing or housing 1, at the upper end thereof. A handle member 27 is secured to the top 25, whereby the latter may be readily removed or placed in position, when desired. I

lVhile we have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing fro-m the spirit or sacrificing any of the principles of the invention.

Having thus described our invention, what we claim is 1. In a filtering device, a main casing pro-' vided with inlet and outlet pipes, an annular inwardly inclined flange fixed to the inner wall of said casing adjacent the bottom thereof, an inner filtering casing provided upon its lower edge with an outwardly inclined do-wnwardly-extending flange, a pack ing ring arranged between said first-named flange and the wall of the main casing upon which the flange of the filtering casing is adapted to seat, and means secured to the inner wall of said main casing adjacent its upper end to cooperate with said filtering casing and removably retain the same in position upon said packing ring.
